CONDUCTOR SUPPORT.

Application led September 23, 1925. vSerial No. 58,076.

AlVly invention relates to a supporting de vice for electric conductors and has par ticular reference to `a. device for supporting a trolley wire and simultaneously there-r with a cable known as a feeder conductor if it is electricallyconnected to the trolley conducto-r through the medium of the, supporting device or otherwise, but which may be insulated from the supporting device and trolley wire if desired.

One of the objects of my invention is to provide a device which can be secured to an overhead support and which will support the conductor independently of the clamping means or trolley wire and for securing the conductor and trolley wire in position and which is or is not electrically connected with the trolley wire when the trolley conductor is clamped into position depending whether the conductor is insulated or not.

My invention resides in the new and novel construction, combination and relation of the various parts hereinafter fully dev scribed and shown in the drawing.

in the drawing:

Fig. 1 is a side view of my invention in combination with a trolley wire and a feeder conductor.

Fig. 2 -is an end view of Fig. 1.

Fig. 3 is a view in partial section taken on the line 3-3 of Fig. 1.

' Fig. l is an end view of my invention in which the clamping members are shown in a position to receive the conductor which is shown as insulated from its suport.

pin the preferred embodiment of my invention I Vemploy a body memberl which provided with a boss 2 and which is usually internally threaded to receive the threaded stud of an overhead support. rlhe lower end of the body member 1 is provided with a 'lip 3 to engage one of the side grooves in a trolley wire. This lip 3,' however, may be arranged to receive a perfectly round sectioned conductor or trolley wire if desired.V Thebody member 1 is also provided with a transverse passage 4' to receive a transyerse bolt 5 and Vnut 6 there- Projecting from theinner face of the member 1 is alp '7 which. forms acurved seat 8 to receive and support the conductor 9` or 9 which is insulated (Fig. 4).

The clamping memberl is furtherprovided' with a longitudinal groove 10 the surface of` which coincides with vthe seat 8 of the lug 7 to providev a further means 4of ieceiving and gripping the conductor 9 or The support is also provided with a clamping member 11 which has a transverse opening thereinand having one portion 12 of the opening to register with the opening e' in the member 1 for the reception of the bolt 5.` The transverse opening is also provided with a portion 13 intoV which projectsthe lug '7.v The clamping` member 11 is provided with `a'longitudinal groove 14s having a circular seat and which cooperates with the groove 10 to receive and clamp the conductor 9 or 9 and there is also provided at the lowerend of the memb'erv11 a lip -1'5- to engage a groove in one side of the-trolley wire 16. f

The installation and operation 0f my invention consists Vusually in first installing the member 1 upon a support by either rotating the device into engagement with a vhanger or support already installed or rotating the hanger or support Vinto engagement with the member 1 and then positioning the hanger or support in place. The

,nut 6 is then loosened up but not entirely `removed from the bolt 5 andthis will permit the clamping member 11'tobe moved away from the member 1 and lowered as lshown in Fig. L1- thereby leaving the seats 8 and 10 free` to receivev the conductor 9 or.9.

'the trolley wire '16, therefore, `when the After thel conductor 9 or 9 has I rbeen positionedV as shown in Fig. 4, the.

operator is installing the device in connection with the two conductors it is only necessary for him to consider one conductor at a time, that is, he first positions the conductor 9 or 9 inV place and he is then free to give attention only to the positioning of the trolley wire 16 and it will be readily understood that this is a Considerable advantage when installingya pair of.

conductors or wires.

It is usual in installingconductors of: this character to stretch the conductors out for aV considerable distance and ythen to draw them into a reasonably taut condition and where my invention is employed it assists in* supporting and positioning the conductor 9 or 9 independentV of the trolley wirelGV andif the conductor 9 or 9" is of considerable size it permits the conductor to be drawn much tighter before theA clamping member 11 is drawn into position as it is common practice to place the supporting devices quite frequently along the length of the conductor.

My invention being made of metal acts as a means of` electrically connecting the conductors 9 and 16 and, therefore, if the conductor 9 is the one connected to the source of power and since it is not insulated, it acts as. a feeder cable to the trolley 16 through t-he medium of'my improved support. p

IfI desired the conductor 9` may be bare and a short length of insulating'material surround the conductor when the support is used thereby insulating the conductor from the support as effectively asrthougli the conductor were insulated throughout its length, and this shortI length of insulating materiall may be al short length of' rubber hose, or a tube ofv porcelain, mica, fibre, etc., all wellknown to those skilled' in the l art.
